Welcome to the GWTW Forum.
Guests (non-registered users) can view the forum but are unable to post.  If you don't have anything to say then why would you bother to register?
One of the most popular sections of the GWTW Forum has long been the Swap Meet.  A great place to sell old, seldom flown kites or to get great deals on used (gently flown) kites.  Only registered users can see the Swap Meet section, let alone wheel and deal.  1000's (literally) of kites have changed hands thanks to the Swap Meet.
There are several more benefits to being a registered user, but you'll have to join our little community to find out all the "secrets".

Stress risers are most significant at corners, welds, connections, etc.
The bigger the change, the more significant the stress riser.

Just as plugging the small end of a spar can significantly increase the allowable load, sealing a cardboard box with tape can make it strong enough to stand on. Don't try that with an open ended box.

Stress risers along the length are pretty much insignificant compared to other items like the standoffs, where the ferrule at the center T ends in the female lower spreader and if the LS is fully seated into the leading edge connector.

Walk around your house and you'll probably see cracks emanating from the corners of void areas like windows, door frames and walkthroughs.

Hope that helps.

Even rounding the edges of your spars a bit will help their life expectancy.

The Infinity comes with plugged ends on the lower spreaders. Pretty cool in a not super high priced kite.  Smiley

I've managed to break BD Nitros a couple of times being a little too aggressive with them. They are quite stiff and a bit brittle. Great stick however.

The PTs seem to take more abuse but then they are not as stiff.


BD never fail...You can send me the others Wink

Yes they do!  In the past 3 months I've broken two BD Nitro lower spreaders when doing aggressive Flapjacks.  Both times they snapped in between the standoffs!  Not the fault of the rod, I was flying to some funky music at the time and got carried away  Cheesy

Regardless, the BD rods are a huge step up in the sexyness department and will get you more chicks when you fly them.

The above claims of increased chicks have not been verified by the FDA or the AKA nor are they endorsed by the poster or this forum.  BD spars are not designed to treat hair loss, poor fashion choices, odors, balding, bad toupee's or over-sized beer bellies.  Results may vary depending on the light of day and intelligent level of the chicks being attracted.  Use only as directed and at your own risk.

I thought it was the large buggy with big honkin' tires that attracted the chicks.  And the really shiny buggies could sometimes offset the "hair loss, poor fashion choices, odors, balding, bad toupee's or over-sized beer bellies" if the sun was glinting off the polished frame just right.  

Heard there are even pictures floating around  Roll Eyes
